Learning Objectives and Outcomes

In this lecture you will:

• listen and participate in a short discussion about the results of the check in survey
• listen to a lecture about peak detection, how to implement it in MATLAB, and some syntax differences between MATLAB and C++

By the end of this lecture you should be able to:

• complete exercises 4–5 on the lab (6 is extra credit)

Lecture Content

ENGR 029 SP23 Check-In Survey Results

Baeldung Peak Detection

See example MATLAB code in Lab 2 Github; if you don’t have access, let me know and I will set you up.

Major differences between MATLAB and C++

• Arrays:
  • index using () instead of []
  • first index is 1 instead of 0
  • Example:
    • to get the first element of an array myPeaks:
      • MATLAB: myPeaks(1)
      • C++: myPeaks[0]
• For loops
  • To make a for loop, MATLAB has a shorthand when you know you are increasing by 1 each time.
  • Example, iterate over all elements of a four element array.
  • MATLAB: for j = 1:4
  • C++: for (int j = 0; j < 4; j++)
